Application to request http2 content with multiple streams

[Rajvardhan Deshmukh]

Hi All,

I have 2 questions:

1. I intend to write an application to get content over HTTP2 over
multiple-streams over one connection. With the command line tool [1] i
could get content over single stream.

I found this snippet [2] that helped me write this [3]. But I need to
include the TLS version and ssl certificate details as specified with
the command line tool [1]

Can you tell me which additional symbols i should use to set the
certificate?

2. I also need to identify the api which requests chunks of data (so
that not all response data is written to the memory at the same time,
but as multiple of chunks). (Just like the 'iter_content(CHUNK_SIZE)' in
the requests [4] python library)

Thanks,
Raj

The command line tool still only does transfers serially, but it will reuse
the same connection and thus do multiple streams if it can. Just not
multiplexed.

Add "--libcurl template.c" to your command line arguments and you'll get a
good start!

libcurl always delivers the response chunk by chunk with the write callback:
